By far the best oil filter I haver used period!

There is a noticeable smoother run for my old 04 Rav4. The first one I used was great . I went to a quick oil change place, they used some house brand. There was a noticeable change in how the engine sounded and even idles. Just did my own change back to K&N, smooth and quiet idle and running .

Great oil filter, and for a great price too. When you pick this filter up, you can tell it's packed full of filter material, which is going to keep your oil cleaner between oil changes. I honestly could not recommend K&N enough.

K&N Oil Filter
  • K&N Performance Silver Series
  • For Synthetic and Conventional Oils

It is an oil filter. After ordering the filter, it showed up pretty quick. I'm happy with how well it filters the oil. This is my fifth time using this filter with synthetic oil and so far I haven't had my engine explode or my car spin off the road and flip so I am pretty satisfied with this filter. Plus, it's black (and everyone knows that's the coolest color for filters - LIKE A REBEL!) Threading is correct size to my car so it goes on without the need for a hammer. Comes off without a grinder, too! I just can't say enough good stuff about this filter.

K&N Oil Filter; Billet
  • Billet Aluminum Housing
  • Washable and Reusable
Jason, Sydney Australia
I installed it as per instructions I put PTFE on the o-ring and connecting the filter to the engine it seized that hard that a screw driver and hammer was needed being billet aluminum it didn't like it too much. I was able to re thread it again the canister spins off but left the filter element and connecting piece still on the vehicle both off the threads are a right hand type. I spoke to K&N they were very helpful and resolved the matter immediately. Hopefully I don't have this prob with the second one. The dirt it collected plus the magnets that were visibly able to see was impressive. I still would like to know the microns it filters down too.
